Based on Interaction energy of solid ball, the new particle damper is designed which can be used in a high temperature and high shock energy. To verify the design of the damper, a falling weight Impact test rig is designed, a sensor, data acquisition card and computer hardware constitutes a signal test system. Experimental results show that the particle diameter is the biggest impact for the role of the particle damper , the characteristics of the displacement curves are increased at first and then decreased, the opposite effect of the time. At the same time filled with particles and the degree of damping rod embedment also have an impact on energy consumption.

Leaf springs are the traditional suspension elements, occupying a vital position in the automobile industry. This paper deals us the replacement of existing steel leaf spring by composite leaf spring. The dimensions of existing middle steel leaf spring of commercial vehicle (Tata ace mini truck) were taken and fabricated using a specially designed die. Single leaf of the suspension springs, each made up composite with bidirectional carbon fiber reinforced plastic (CFRP), bidirectional glass fiber reinforced plastic (GFRP) and hybrid glass-carbon fiber reinforced plastic (G-CFRP), was fabricated by hand layup process. It is to be mentioned here that the cross sectional area of the composite spring same as the metallic spring. A low velocity impact test rig was fabricated in the laboratory with loading set up. The composite leaf springs were tested with the low velocity impact test rig. By using the low velocity impact test rig, the deflection due to various drop height were measured.

AbstractThe structural characteristics of a subsurface cage system for sea cucumber, Stichopus japonicus, grow-out were analyzed by using numerical modeling techniques. The cage system was constructed of polypropylene pipe and netting and weighted to sit on the seafloor bottom. Inside the cage, concrete blocks were used for animal aestivation and weight and a thin-plated device was mounted for animal movement. Environmental loads on the structure, resulting from a prescribed irregular wave field with and without currents, were first determined with a Morison equation-type finite element model. The structural response of beam and truss cage components was then calculated with the software MSC.MARC/Mentat. In addition to the irregular wave and current input forcing parameters of the structure, response was also calculated for possible forces incurred during lifting operations. Reaction loads, bending moments, axial tensions, and von Mises stresses of the sea cucumber cage structure were calculated for evaluation. The results of the study indicate that the combination of numerical model analyses presented can be used to assess structural integrity of these subsurface cage systems. These techniques will become more important as the industry expands and economics of scale promotes the construction of larger sea cucumber containment structures.

Hydraulic hybrid system solutions are promising in the quest for energy efficiency in heavy construction machines. Hardware-in-the-loop simulations, where hardware is included in software simulations in real time, may be used to facilitate the development process of these systems without the need to build expensive prototypes. In this paper, the displacement actuator of a prototype pump used in a hardware-in-the-loop simulation test rig is modelled and validated against hardware, in order to draw conclusions regarding its dynamic behaviour in a future control design. The results show that the dynamic response of the modelled displacement actuator is mainly determined by the system pressure as well as the response and geometry of the control valve.
